UNITED STATES SHERMAN M. FAIRCHILD, OF ONEONTA, NEW YORK.

PLATE PACK.

Application filed September y23,1918.

Be it known that I, SHERMAN M. Fain- CHILD, a citizen of the United States, residing at Oneonta, in the county ot Otsego and. State ot New York, have invented ner.' and useful Improvements in Plate Packs, ot which the following is a specification.

This invention relates to photographic plate packs, which essentially combine the usual commercial packages in whichv the plates are arranged for sale, and the adapter through Twhich the plates are exposed in the camera..

The improvement contemplates theemployment of a box in which the plates .are sold comprising telescopic sections so constructed that the. sensitized plates contained therein may be loaded in the adapter, exposed, changed and removed from the adapter in full daylight Without detriment thereto.

The improved plate pack is constructed to simulate the usual commercial plate package in size and appearance, and in detail in` volves but a slight expense in manufacture over such commercial package. However, such detail permits the use ot the plate pack in an adapter tor the successive exposure oit the plates in the camera, so that the usual commercial package Will serve to retain the plates until they are desired for develop ment.

Structurally, the improved pack combines a box-like member made up ot telescopic sections, of the material of the usual comniercial packages, or other material, as desired.I @ne of the sections will receive the plates, While the other, which serves as a cover, is

arranged so that a simple complete telescopicl opening and closing thereof, removes the forward or exposed plate to a positiony iu rear ot but as a member of the plate pile. '.lherctore, the plate pack will enable the user to expose the plates successively in the camera, Without possibility ot light admis." sion to the fresh plates, and simultaneousl)r arrange the exposed plates in the original package form.

The invention will be described in the folD lowing specification, reference being had to the accompanying drawings, in Which- Figure l is a front elevation partly broken out of the improved plate pack, the outer plate piles. as will later appear'.

Figure 4 is a vertical section of the improved plate pack With a slightly modiied plate operating means.

Figure 5 is a front elevation partly broken out.

The improved plate pack, in both the preferred and modified forms, is here shown as comprising a box-like member, including au inner section l and an outer section 2. The box-like member is preferably constructed ot cardboard, as is the usual plate package of commerce and closely resembles such package in sis/.e and shape. The inner section is ot' a vwidth, length and thickness to rer-,ei ve and house the desired number of plates. and in specific formation has the usual hack 3, side Walls et, and bottom edge ivall 7, the latter being, however, of someivhat greater thickness than the usual box end.

The :trout of the section l has a rectangular shaped opening G cut out of dimensions slightly smaller than the plates used to keep the latter tromialling out. .is aforesaid, the upper end of the. section i is open except tor the. guide ledge 7. Fig. l, or 7, Fig. 4t. This ledge is Vformed to guide the platesl from the exposing` position to a position in rear of the The gui de ledge is secured to the side walls oi the section, and is of a generally right-angled triangular shape in cross section, With the upper side straight as in Fig. et or slightly rounded as in Fig. 2. The toi-ward wall ot the `ledge is spaced from the top ot the front. wall S oi the section to permit a plate to pass tlienfbetween, while the rear edge oi the ledge is similarly spaced from the back. oi the section. The upper surface ot the ledge is inclined toward the back or rear of the section to direct the lower edge of the plate being shifted.

The outer section of the pack 2 is fitted to telescopic-,ally embrace the inner section l and is therefore open at its lower end Wall l and 2. The upper end wall of section 1 extends at beyond the side walls to form shoulders i9. and members 5 of section 2 are provided with pin holes for engagement with an adapter.

Uf course, before loading the plate pack ter, the plates must be protected against light entrance through the two coextensive openings in the frontI walls of sections l and Q F or this purpose a piece 1" of cardboard or other light p of material the length and width of the plate is arranged in front of the first plate and covering.' the openings. This cardboard a: a dummy plate the first outward movement ot the outer section, leaving the lirst' sens "e plate in position to be eX- posed. Exposure in the camera will be had with the sections in closed relation, or in open relation, as desired, as in either position the foremost plate is exposed to the light through the lens.

The meeting edges and portions of the sections l and 2 are, of course, to be formed to avoid light entrance, the detail being here shown right angled as interfitting of the parts.

Having thus described the invention, what is claimed as new, is

l. A plate pack in which the plates are initially assembled for sale as a complete commercial package, said pack comprising telescopically related open faced sections, and means arranged in said plate pack to shift first the free end and then the other end of the plates in the pack from one position to another in the telescopic movement of the sections.

2. A plate pack comprising telescopic sections both open throughout the sensitized area of the contained plates, land a dummy plate initially rendering the interiorl of the pack light proof against such openings, and plate shifting means operated. in the movement of the sections to move rt-iarwardly rstthe free end and then the other end of said plates.

A plate pack comprising an open faced plate-receiving section, an open faced operating section having telescopic relation to the receivinp section, and means carried by the operating section to engage and movel rearwardly first the free end and then the other end of the foremost plate in the rcceiving section from such position.
